I just had some major attack undiagnosed by the emergency room doctor (that is, a totally WRONG diagnosis) I am searching for what those symptoms are. The pain was so intense last night that I went to the emergency room thinking I was having aa heart attack (I'm 51). Not so. the pain went down considerably after 30 minutes, leaving me very weak all day today with continueing pain over what I can best ascertain as my spleen.Any sites with this info?
